Evaluation of adsorptive characteristics of PMMA-co-poly(HEMA-co-MMA) electrospun nanofibers for the removal of cationic dyes

The adsorption characterictics of PMMA-co-poly(HEMA-co-MMA) electrospun nanofibers werestudied for the removal of Basic Blue ۱۱ (BB۱۱). The structure of prepared nanofiber was confirmedusing Fourier Transformer Infrared (FT-IR), Thermogravimetric Analysis (TGA), and ScanningElectron Microscopy (SEM). The results demostrated the maximum adsoprtion capacity of ۹۱.۷۱۲mg g-۱, and removal efficiency of ۲۹.۹ %. Moreover, isotherm and kinetics of adsorption comfimedto Freundlich isotherm and pseudo-second-order adsorption kinetics, respectively. This studyproposed the successful and potential application of nanofibers for the removal of cationic dyes.
